Hi -
Just curious what intensity levels and photoperiod people are using with XR15s over an 18" deep tank (like a 50 breeder). I'm using the standard mounting arms, so about 9" above the water surface, and the top of the sandbed is about 15" below water surface. I'm also using the 80 degree lenses, not the 120 degree lenses.
Thanks!
Larry
